The rotation injecting mechanism of slipmat injection mold
Technical field
The present invention relates to a kind of injecting mechanism, particularly relate to a kind of rotation injecting mechanism of slipmat injection mold.
Background technology
Plastic gridding holding tray (pallet) is the handling backing plate be made up of the load face and fork truck socket that can carry some number of articles used for the ease of cargo handling, transport, keeping and dispensing etc.Along with the development of logistics, it is more and more extensive that plastic gridding holding tray uses, wherein especially two-sided upper lower web plate one grid tray.But current two-sided upper lower web plate one grid tray, its structure is all similar to application number for disclosed in the patent document of 200920196444.1.The shortcoming of the pallet of this structure is: in use, easily skids between pallet and fork truck; When stacking, also easily skid between pallet and pallet, there is potential safety hazard.For this reason, the present inventor once designed a kind of slipmat of the contact site, fork inlet hole position for being arranged on grid tray and fork truck, effectively solve easy slippage problems between pallet and fork truck, but this slipmat wearability requires, causes manufacturing cost also very high high.For this reason, the present inventor dreams up again the slipmat that a kind of slipmat base and slipmat lid bi-material are made, and wherein slipmat submount material is comparatively cheap, but is limited to current Tool and Die Technology, and this imagination can only be a kind of imagination, cannot realize.
Summary of the invention
For prior art Problems existing, the invention provides the rotation injecting mechanism of slipmat injection mold of a kind of low cost of manufacture, environmental protection, slipmat is come true by bi-material injection mo(u)lding.
For realizing goal of the invention the technical solution used in the present invention be:
The rotation injecting mechanism of slipmat injection mold, comprise compound plate and lower compound plate, cavity plate is provided with between upper compound plate and lower compound plate, core plate and ejecting mechanism, described cavity plate is fixed on described upper compound plate, described core plate is fixed on described lower compound plate, the ejector retainner plate of ejecting mechanism is located between described core plate and described lower compound plate, described core plate is provided with core, described cavity plate is provided with die cavity, it is characterized in that: described die cavity is divided into two injection zone, one of them is the slipmat base injection zone that slipmat base can be made shaping, another is the slipmat lid injection zone that slipmat lid can be made shaping, described core plate and described lower compound plate can rotate with injection machine 360 °.
The rotation injecting mechanism of slipmat injection mold of the present invention, by the slipmat base of slipmat and the injection mo(u)lding at twice of slipmat lid, thus makes two parts can adopt different material injection.Because slipmat base is fixed on plastic gridding holding tray, do not slide between the two, therefore less demanding to the wearability of slipmat base, this just can adopt the waste material injection moulding slipmat base of recovery; And slipmat lid will with the fork contact friction of fork truck, therefore require higher to the wearability of slipmat lid, need with original-pack plastic raw materials injection moulding slipmat lid.The proportion of slipmat base shared by whole slipmat is comparatively large, therefore can significantly save cost of material of the present invention, and be recycled by waste plastic, decrease the pollution to environment.
Below in conjunction with accompanying drawing, embodiments of the invention are described further.
Accompanying drawing explanation

Fig. 2 is the structural representation of die cavity in Fig. 1.
Detailed description of the invention
As shown in Figure 1-2, the rotation injecting mechanism of slipmat injection mold, comprise compound plate 1 and lower compound plate 5, cavity plate 2 is provided with between upper compound plate 1 and lower compound plate 5, core plate 3 and ejecting mechanism 4, described cavity plate 2 is fixed on described upper compound plate 1, described core plate 3 is fixed on described lower compound plate 5, the ejector retainner plate of ejecting mechanism 4 is located between described core plate 3 and described lower compound plate 5, described core plate 3 is provided with core, described cavity plate 2 is provided with die cavity, described die cavity is divided into two injection zone, one of them is the slipmat base injection zone 21 that slipmat base can be made shaping, another is the slipmat lid injection zone 22 that slipmat lid can be made shaping, the core coordinated with die cavity is also divided into two injection zone, but the structure of two injection zone is the same.Described core plate 3 can rotate with injection machine 360 ° with described lower compound plate 5 and ejecting mechanism 4.
Operation principle of the present invention is:
This double-colored slipmat need production injection moulding on specific double coloured plastic injection machine.
Mould is fixed on specific double coloured plastic injection machine, first at slipmat base injection zone 21 injection moulding slipmat base.After injection moulding completely, mould die sinking, namely die cavity, core die joint are separated completely, and core position entirety rotates 180 ° along with injection machine, makes the slipmat of injection formed base rotate to slipmat lid injection zone 22.So latter two injection made showerhead injection moulding simultaneously, slipmat base injection zone 21 injection moulding slipmat base, slipmat lid injection zone 22 is injection moulding slipmat lid on the slipmat base of former injection formed.Two injection made showerheads all injection moulding complete rear mold die sinking, the demoulding is carried out after completing whole injection moulding here in slipmat lid injection zone 22, the slipmat base of slipmat base injection zone 2 injection formed with core then 180 ° rotate to slipmat lid injection zone 22 greatly, and then matched moulds, two injection made showerhead injection mouldings simultaneously again, so produce always repeatedly.Both injection time was saved, raising efficiency; The requirement that some identical products need unlike material, different color can be met again.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just design according to the present invention can make many modifications and variations without the need to creative work.Therefore, all technical staff in the art on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should fall within the scope of protection of the present invention under this invention's idea.
